2000: Problems with his eyesight end play-by-play career.
Signature phrases
In his autobiography, Ain't the Beer Cold!, Chuck Thompson explained how he came to use (and stop) his two signature phrases:

Ain't the beer cold!: "I got that phrase from Bob Robertson, a spotter who worked with me on Baltimore Colts football games [that were sponsored by the makers of National Beer]. ... Eventually I received lots of mail from people ... [who] felt they shouldn't have to put up with my ad libs about beer with all the beer advertisements they were already exposed to, and I thought they had a legitimate beef. So, I stopped using the line sometime in the 1970s."

Go to war, Miss Agnes!: "That was something I picked up from Bob Sharman, a golfing friend and neighbor. When his putting didn't improve after he read a book on the subject, Bob would grumble, "Go to war, Miss Agnes," after missing a putt. I phased that expression out of my play-by-play lexicon as the Vietnam War dragged on."
